As a part of the Dev Derby he's participating in, Chance Garcia has put together a list of books that he sees as beneficial to developers out there to hone their craft.

Our book selections are not limited to our respective Languages. I thought I would share my list with everyone. The first 2 (GoF design patterns and Patterns of enterprise application architecture) really just need to be in every developer's library. The rest are a collections of books I've read and liked as well as recommendations from developers I like and respect.
